"Access Hollywood" co-anchor Billy Bush and U.K. television and theatre star Denise Van Outen host the show, which kicked off a nationwide search Jan. 7 to find actors to play the lead roles of Sandy Dumbrowski and Danny Zuko in the forthcoming Grease revival.

Tony Award winner Kathleen Marshall (The Pajama Game), who will direct and choreograph the new Broadway production, served as one of the three judges of the weekly program. Her fellow judges included Grease co-creator Jim Jacobs and theatre producer David Ian.

The 12 finalists are now narrowed down to four: Possible Dannys are Austin Miller ("Hot Danny") and Max Crumm ("Slacker Danny"); possible Sandys are Ashley Spencer ("Ballerina Sandy") and Laura Osnes ("Small-town Sandy"). Who will be cast in the roles will be revealed at the conclusion of the hour-long March 25 broadcast. Although the judges were able to save contestants throughout the competition, the final decision has been left to the voting public.

Paul Nicholas and David Ian Associates, Nederlander Presentations and Phoenix Productions will produce the Broadway run of the show. The capitalization is $10 million.

The new Broadway production will feature the Jim Jacobs-Warren Casey songs made famous by the original musical — including "Summer Nights," "Greased Lightning" and "We Go Together" — as well as the four additional film songs: "Grease is the Word," "You're the One That I Want," "Hopelessly Devoted to You" and "Sandy" interpolated into the score.

Tickets are on sale through Ticketmaster outlets. Group sales for Grease are available by calling Nederlander Group Sales at (212) 840-3890.
